在爱尔兰种植的未加工燕麦谷物中调查了42种真菌毒素的自然共生。样本集包括2015-2016年间收获的208种燕麦作物，采用传统、有机或无麸质耕作系统生产。鉴定出一系列不同的毒素，包括主要的A型（新茄醇、HT-2和T-2毒素、T-2三醇和T-2-葡萄糖苷，共出现在21个样品中）和B型（脱氧雪腐镰刀菌醇、雪腐镰刀菌醇和脱氧雪腐镰刀菌醇-3-葡萄糖苷）、enniatins （B1、B和A1，共出现在12个样品中），以及beauvericin、alternariol、霉酚酸和sterigmatocystin。研究了播种季节、年份和生产制度的影响，最终表明后者因素可能比其他因素对燕麦中某些真菌毒素的产生有更大的影响。最常被量化的化合物是HT-2（51%）和T-2（41%）毒素，与传统生产的燕麦相比，无麸质燕麦含有明显较低浓度的HT-2。虽然本研究中燕麦样品中霉菌毒素的含量和浓度应该通过加工而大大降低。然而，由于霉菌毒素的发生明显受到多种因素的影响，应进行对照田间试验，以确定最佳农艺做法并减少霉菌毒素的产生。此外，这项工作强调需要使用比传统筛选和管制毒素具有更广泛特异性的多残留分析方法定期检测谷类食品，以获得关于迄今为止很少调查的几种真菌毒素发生情况的知识。
The natural co-occurrence of 42 mycotoxins was investigated in unprocessed oat grains grown in Ireland. The sample set included a total of 208 oat crops harvested during 2015–2016 and produced using conventional, organic, or gluten free farming systems. A range of different toxins was identified, including the major type A (neosolaniol, HT-2 and T-2 toxins, T-2 triol, and T-2-glucoside, co-occurring in 21 samples) and B trichothecenes (deoxynivalenol, nivalenol, and deoxynivalenol-3-glucoside), enniatins (B1, B, and A1, co-occurring in 12 samples), as well as beauvericin, alternariol, mycophenolic acid, and sterigmatocystin. The influences of sowing season, year, and production system were investigated, eventually indicating that the latter factor may have a higher impact than others on the production of certain mycotoxins in oats. The most frequently quantified compounds were HT-2 (51%) and T-2 (41%) toxins, with gluten free oats containing significantly lower concentrations of HT-2 compared to conventionally produced oats. Although the prevalence and concentrations of mycotoxin found in oat samples in this study should be substantially reduced by processing. However, as mycotoxin occurrence is clearly influenced by multiple factors, controlled field trials should be carried out to define optimal agronomic practices and mitigate mycotoxin production. Furthermore, this work highlights the need for regularly testing cereal-based foods with multi-residue analytical methods with wider specificities than the traditionally screened and regulated toxins, to generate knowledge on the occurrence of several mycotoxins that are, to date, rarely investigated.
